ASTM A789 A790 UNS S31803 Duplex Steel S31803 2205 Seamless Pipe Tube
1. ASTM A 790 UNS S31803 Duplex Steel werkst off nr. 1.4462 Pipes & Tubes Manufacturer, Exporter & Suppliers. Duplex SS S32205 Seamless Pipe, SAF 2205 Pipes, ASTM SA789 Duplex steel tubes, Duplex Steel 2205 Pipes, S31803 Duplex Steel Seamless Pipe Tube Manufacturer in China.
ASTM A789 is the Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service.
ASTM A790 is the Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe.
ASTM A789 and ASTM A790 Duplex stainless steel pipe is typically manufactured using the seamless or welded process. For seamless pipes, a solid billet of the material is heated and then passed through a piercing rod to create a hollow tube. The tube is then rolled to the desired thickness and cut to length. For welded pipes, the material is first formed into a flat sheet. The sheet is then rolled into a tube shape and welded along the longitudinal seam. The welded pipe is then heat treated to remove any residual stresses and to improve its mechanical properties.
